I mean the "type" for the corso is not set. Different head structures, temperment issues, confirmation period. Years ago, you could never find a corso with a reverse scissors bite, you would only see a corso with minimal white and most times on the chest. You have corso with boxer influence, ab influence and ddb influence. I love the breed but whats happening to the corso is somewhat similar to the american bulldog, various strains which means people are working on their agenda and not the breeds. Just look at italian corsos versus the american or the canadian corso. The size of the corso is not even set, smaller dogs in europe when the first ones to come from europe were true mastiff size.
